Subject: [PATCH v2 4/7] memory-hotplug: ia64: suitable memory should go to ZONE_MOVABLE
Date: Mon, 21 Jul 2014 11:46:39 +0800 [thread overview]
Message-ID: <1405914402-66212-5-git-send-email-wangnan0@huawei.com> (raw)
In-Reply-To: <1405914402-66212-1-git-send-email-wangnan0@huawei.com>
This patch introduces zone_for_memory() to arch_add_memory() on ia64 to
ensure new, higher memory added into ZONE_MOVABLE if movable zone has
already setup.
